Question

two pipes running together can fill a cistern in 4 4/5 minutes if 1 pipe take 4 minutes more than the other to fill the cistern find the time in which each pipe would fill the cistern

Answer 1

Step-by-step explanation:

Let one pipe fills the cistern in x mins.

Therefore, the other pipe will fill the cistern in (x+3) mins.

Time taken by both, running together, to fill the cistern = 3 1/13 mins = 40/13 mins

Part filled by one pipe in 1 min = 1/x

Part filled by the other pipe in 1 min = 1/(x+3)

Part filled by both pipes, running together, in 1 min = 1/x + 1/(x+3)

Thus, one pipe will take 5 mins and other will take {(5+3)=8} mins to fill the cistern.
